             Summary: Queue Management API - rephrase error messages
                 Key: YARN-8678
                 URL: https://issues.apache.org/jira/browse/YARN-8678
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Akhil PB
            Assignee: Akhil PB


1. When stopping a running parent queue, error message thrown by API was not meaningful.
For example: When tried to stop root queue, error message thrown was  {{Failed to re-init queues : The parent queue:root state is STOPPED, child queue:default state cannot be RUNNING.}}  
It is evident that root queue update failed, but the message says {{queue:root state is STOPPED}}.

2. While tried to delete a running leaf queue, error message thrown by API was not meaningful.
For example: Error message was {{Failed to re-init queues : root.default.prod is deleted from the new capacity scheduler configuration, but the queue is not yet in stopped state. Current State : RUNNING}}.
Clearly deletion of queue root.default.prod failed with error, but the message says {{queues : root.default.prod is deleted from the new capacity scheduler configuration}}.
